Maybe you refer to --mpi option (--hpc doesn't exist).
BTW, also with this option (--mpi) I got the error
|runCode: Fail to run
|mpiexec -machinefile MPI_HOSTFILE -n 1 out_WaveWind_VarS-T_G3

|Open MPI does not support recursive calls of mpiexec

Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[5273,1],0]
Exit code: 1
and in the error file
